Nest Devices Operating as Stealth Bluetooth Beacons

I recently noticed that my Thermostat E and Nest Cam devices both seem to constantly broadcast identifiable bluetooth signals long after the initial setup process, and Nest/Google locks out any ability for the user to disable this behavior. There's no benefit to the owner for having bluetooth broadcasting outside of setup mode, but Nest/Google get to quietly conscript their customers into an automatic bluetooth beacon-like location tracking network. Nest needs to provide transparency on anything they do with data harvested from/by our devices bluetooth identifiers, and make perpetual bluetooth an optional feature.
